TECHNICAL FIELD

The invention relates to a headset communications system with a base unit and headset.

BACKGROUND

Wireless headset systems for use in offices and contact centres are well known. They normally comprise a wireless headset with a headset transceiver and a headset base with a corresponding headset base transceiver. The headset transceiver and the headset base transceiver can be connected by a radio link. Wireless headsets following different radio standards are known, but DECT (Digital Enhanced Cordless Telecommunications) and Bluetooth™ are the most prevalent. Bluetooth™ is the prevailing radio standard used by mobile phones and headsets, and DECT is the prevailing standard used by office headsets and their base cradles.

DECT is also the prevailing radio standard for cordless phones, i.e. between the handset and its base. DECT devices can be GAP compatible. GAP is acronym for Generic Access Profile and describes a set of mandatory requirements to allow any conforming DECT Fixed Part (base) to interoperate with any conforming DECT Portable Part (handset or headset) in order to provide basic telephony services.

DECT phones are sometimes sold with more than one handset. The extra handsets are only provided with charging cradles, as the extra handsets are communicates with the main headset base. A system with a main base, a main handset and one or more extra handsets also provides the possibility for intercom features, whereby people in a home can communicate with each other via the handsets. An example of a Cordless DECT phone with two extra handsets is Panasonic KX-TG6411.

It is possible to use GAP compatible handsets and headsets with GAP compatible phone bases. Thus, a consumer can buy a GAP compatible DECT headset and connect it with the base station of his GAP compatible DECT phone in order to make hands free telephone calls. In this case, the headset base station functions as a charger only, as the headset transceiver communicates directly with the telephone base transceiver.

Likewise, a headset base unit is a unit, which is arranged between a headset and one or more telecommunication devices, such as a PSTN (Public Switched Telephone Network) desk phone, and IP (Internet Protocol) desk phone, an IP soft phone (installed on a computer) and a mobile phone. The headset base unit comprises a headset holder for holding the headset when not in use. The headset comprises one or two earphones and a microphone. The headset base unit is typically placed on a desk beside a telephone and/or a PC. When the user wants to use the headset, he picks up the headset from the holder and arranges in on his ear or head. The headset can be connected to the headset base unit by a wire or wirelessly. In both cases the user's hands are free for other purposes such as using the computer or handling papers while communicating via the headset.

GN 9350 is an office headset system comprising a headset base unit to be placed on a desk surface and a wireless headset, which can be placed in a headset holder of the headset base unit when not in use. The headset is recharged when placed in the holder. The headset base unit can be simultaneously connected to a desk phone, which can be a PSTN phone or an IP Phone, and a USB socket on a PC. The headset base unit comprises a “telephone mode” button and a “USB mode” button. When the user wants to make or receive a telephone call via the desk phone, he presses the “telephone mode” button. If the user wants to make or receive a call via a soft phone installed on the PC, he presses the “USB mode” button. The buttons are so-called momentary buttons and small indicator LED is arranged at each button. When the button is pressed, the associated LED is turned on, so the user can identify the chosen telecommunication device. This system works well, as the user by means of the LED easily can identify the selected telecommunication terminal.

During an active call, the setup icon 17 has changed to a call option icon 67, represented by a small speaker with a sound wave symbol. By touching this icon, the user gets access to various call adjustments shown in FIG. 9. A “recording” icon 42 shown in the status bar indicates that a call via the PC soft phone is recorded on the PC. However, there could also be a recording function built into the headset base unit 2, so that calls through any of the connected telecommunication devices could be recorded.

FIG. 8 d) “Call Collision”

FIG. 8 d) discloses what is called a “call collision scenario”. There is an active call on the desk phone and an incoming call on the mobile phone. The caller ID 24 of the caller on the mobile phone is shown on the screen just below the status bar. The caller ID is normally a phone number or the name of the calling party. The user now has two options represented by a first call collision icon 68 and a second call collision icon 69. If he touches the first icon 68, he rejects the incoming call on the mobile phone and continues the call on the desk phone. If he touches the second icon 69, he ends the call on the desk phone and receives the incoming call on the mobile phone.

FIG. 8 e) “On Call/Hold”

In FIG. 8 e) a call on the mobile phone is put on hold, which is indicated by the on hold icon 20. By simply touching the on hold icon 20, the user can make the call active again. By touching the icon representing the active call (see FIG. 8 c)), the user can put the call on hold again.

FIG. 8 f) “On Call/Incoming Call on Same Line”

In FIG. 8 f), the user has an active call on the mobile phone while there is an incoming call on the same phone. He now has three options represented by a first incoming call icon 21, a second incoming call icon 22 and a third incoming call icon 23. If he selects the first icon 21, he continues the active call and rejects the incoming call. If he selects the second icon 22, he ends the active call and receives the incoming call. If he selects the third icon 23, he puts the active call on hold and receives the incoming call.

FIG. 8 g) “N-Way Call”

In FIG. 8 g), the user has a call on hold on the PC soft phone, represented by the on hold icon 25, and an active call on the PC soft phone, represented by the on call icon 26. Between these two icons 25, 26 there is a swap icon 62. The user can swap between the two calls, i.e. put the active call on hold and vice versa, by touching the swap icon 62.

FIG. 9 shows how different call options can be adjusted by means of the touch screen. If the user touches the call options icon 67 (see FIG. 8 c)), the call options screen shown in FIG. 9 a) appears. The call options screen comprises a call options menu with a speaker volume icon 70, a mute icon 71 and a start recording icon 72. The screen also comprises a scroll down icon 74, a scroll up icon 75 and an exit icon 73 in the lower end of the screen and a scroll bar 76 in the right side of the screen. Further menu icons, such as “tone setting”, becomes visible by upwards and downwards scrolling by means of the scroll down icon 74 and the scroll up icon 75. The scroll bar 76 indicates which part of the menu that is visible. Alternatively or additionally, the user may scroll by sliding the finger in the direction of the scroll bar 76. If the user touches the exit button 73, the call options menu is left. A selection of the speaker volume icon 70 will be explained below in connection with FIG. 9 b). If the user touches the mute icon 71, the headset microphone is muted. If the user touches the start recording icon 72 all communication is sent by means of the USB cable 64 to the PC 10 and recorded by means of appropriate software. The software can be set to stop recording at the end of a call, or just pause recording between calls. If the user selects the speaker volume icon 70, the screen shown in FIG. 9 b) appears. The screen comprises a speaker meter icon 79 indicating the speaker level, a first adjustment icon 77 with a minus character and a second adjustment icon 78 with a plus character. The user can turn the speaker volume down by touching the first adjustment icon 77 and up by touching the second adjustment icon 78. The speaker meter icon 79 has eight levels and in FIG. 9 b), speaker level four is selected. The speed or the number of steps, speaker volume is adjusted by touching adjustment icons 77, 78 may depend on how long the user touches them. In an alternative embodiment, the adjustment make take place by sliding the finger across the touch screen display 6, so that the speaker volume is adjusted upwards, when by sliding the finger in a first direction and downwards by sliding the finger in the opposite direction. The headset base unit may be adapted to remember the last volume setting for each connected telecommunication device and report the volume setting by sending control signals to the headset when a telecommunication device is selected. Thus, the volume is separately set for the desk phone, the soft phone and mobile phone. The user can leave the speaker volume screen by touching the exit icon 73.

In FIG. 9 c), the user has selected “tone setting” (equalisation) from the call options menu. Here the user can select the sound from the headset speaker to be one of three different types represented by a treble icon 80, a normal icon 81 and a bass icon 82. If he selects the treble icon 80, the sound in the treble area will be accentuated, and if he selects the bass icon 82, the sound in the bass area will be accentuated. The normal icon 81 selects a neutral sound. Preferably, the speaker volume, microphone muting and speaker tone setting takes place in the headset, which means that control signals for adjusting the settings are sent from the headset base unit to the headset. The headset sends status signals to the headset base unit about the settings, so that the display shows the correct levels.

Some of these adjustments can also be carried by means of the headset user interface. It is especially advantageous, if the headset speaker volume can be adjusted by the headset user interface. Thus, the headset volume button 53 shown in FIGS. 5 and 6 is used for adjusting the headset speaker volume, while status signals simultaneously is sent to the headset base unit in order to update the display. In this case, it is optional for the user whether he wants to make audio adjustments by means of the headset user interface or by means of the base user interface. If the user is away from the headset, he will use the headset user interface. If he sits at his desk, he may prefer to use the base user interface.

Alternatively, the adjustments take place in the headset base, in which case control signals are sent from the headset to the headset base in order to adjust the audio settings.

In all cases, status or signals are exchanged between the headset and the base, so that the status information shown on the display of the headset base unit is synchronized with the actual sound setting.

FIG. 10 discloses different views of the display during setup of the headset system according to the invention. If the user touches the setup icon 17 (see FIG. 8 a)), the screen shown in FIG. 10 a) appears.
